In winter or spring, when the temperature plummets, the orchid is susceptible to low temperature frost damage, which seriously affects its growth and ornamental value. So how to carry out first aid treatment after the orchid is frozen, and what follow-up maintenance measures are needed to help our orchid tide over the difficulties and rejuvenate it.
Leaf variations: After frost damage, the most obvious symptoms are water-stained yellow spots, wilting and even blackening of the leaves, and in severe cases, the edges of the leaves will dry up.
Stem damage: Low temperature causes damage to the stem tissue of Orchid junigra, which may shrink, soften, rot, etc., affecting the transport of water and nutrients.
Damaged root system: If the potting soil freezes, it may cause frostbite on the root system, which is manifested as blackening of the root tip, rotten roots or sudden wilting of the whole plant.
Move immediately to a warm environment: Once you find that you are suffering from frost damage, the first task is to immediately move the plants from the cold environment to a warm place (the indoor temperature should be kept at 10-20) to avoid further cooling and damage to the plants.
Defrost moderately: For frozen soil, do not thaw it directly with hot water, but slowly place it at room temperature to thaw naturally to prevent more serious damage caused by alternating hot and cold.
Hydrate properly: After thawing, observe the state of the plant, if the leaves are not completely wilted, you can water appropriately, but not excessively, in order to prevent the root system from being damaged and unable to absorb and aggravate the disease.
Trim the damaged area: Carefully inspect all parts of the orchid, cut off the leaves and stems that are obviously frostbitten, discolored, and rotten, and apply disinfectants such as plant ash or carbendazim to the wound to prevent the invasion of germs.
Adjust the lighting: Frozen monarch orchid needs sufficient scattered light to promote photosynthesis and rejuvenation, but avoid strong direct sunlight to avoid secondary damage to the fragile leaves.
Moderate water control and fertilization: After the root system gradually recovers its vitality, gradually return to the normal watering frequency, following the principle of "seeing dry and wet"; At the same time, the conventional fertilization is suspended until the plant resumes normal growth, and then a thin liquid fertilizer is applied to supplement nutrients.
Change the soil and replant: If the root system is seriously damaged, it is recommended to replace the new soil and replant it in a timely manner, and choose a slightly acidic soil that is loose and breathable, rich in organic matter, which is conducive to the development of new roots.
Ongoing observation and careDuring the whole recovery process, pay close attention to the growth of Monarch Orchid, and if there are signs of pests and diseases, it should be prevented and controlled in time to ensure that it can smoothly get out of the shadow of frost damage and rejuvenate itself.
Although it is shade-tolerant and more adaptable to lower temperatures, it is still susceptible to frost damage in extreme climatic conditions. It is important to correctly identify and take effective emergency response and recovery measures in a timely manner. As long as we take care of it carefully, even the frost-damaged Gentleman's Orchid can rejuvenate and once again show its proud, elegant and dignified posture.
